342 ZOOLOGICAL GEOGRAPHY. [PART 1. 
The butterflies of this sub-region, according to the best esti- 
mate that can be formed, amount to about 650 described species, 
a number that will yet, no doubt, be very considerably increased. 
The genera which appear to be peculiar to it are Hrites (Saty- 
ride); Zeuxidia (Morphide); Amnosia, Xanthotenia, and 
Tanecia (Nymphalide). The groups which are most charac- 
terisiic of the region, either from their abundance in individuals 
or species, or from their size and beauty, are—the rich dark- 
coloured Huplea ; the large semi-transparent Hestia; the plain- 
coloured Mycalesis, which replace our meadow-brown butterflies 
(Hipparchia) ; the curious Elymnias, which often closely resemble 
Eupleas; the large and handsome Thamantis and Zeuxidia, 
which take the place of the giant Morphos of South America ; 
the Cethosia, of the brightest red, and marked with a curious 
zigzag pattern; the velvety and blue-glossed Terinos; the pale 
and delicately-streaked Cyrestis; the thick-bodied and boldly 
coloured Adolias ; the small wine-coloured Tazxila ; the fine blue 
Amblypodia; the beautiful Thyca, elegantly marked under- 
neath with red and yellow, which represent our common white 
butterflies and are almost equally abundant; the pale blue 
Eronia, and the large red-tipped Jphias. The genus Papilio 
is represented by a variety of fine groups; the large Ornithop- 
tera, with satiny yellow under-wings; the superb green-marked 
“brovkeana;” the “paradoxa” group, often closely resembling 
the Eupleas that abound in the same district; the “paris” 
group richly dusted with golden-green specks; the “ helenus” 
group with wide-spreading black and white wings; the black 
and crimson “ polydorus” group; the “memnon” group, of the 
largest size and richly-varied colours; and the “ ewrypilus” 
group, elegantly banded or spotted with blue or green: all these 
are so abundant that some of them are met with in every walk, 
and are a constant delight to the naturalist who has the privilege 
of observing them in their native haunts. 
The Coleoptera are far less prominent and require to be care- 
fully sought after; but they then well repay the collector. As 
affording some measure of the productiveness of the tropics in 
insect life it will not be out of place to give a few notes of the
